What this patent protects

This patent protects an intrauterine contraceptive device with a frame made of a specific metal and a copper component.

USPTO Abstract

An intrauterine contraceptive device may include a frame made completely or partially of a first metal having a first galvanic potential and at least one metallic member coupled with the frame that is made of a second metal having a second galvanic potential different from the first galvanic potential. In some embodiments, the first galvanic potential may be more anodic than the second galvanic potential. In alternative embodiments, the first galvanic potential may be more cathodic than the second galvanic potential. In one embodiment, the first metal is Nitinol, and the second metal is copper. In some embodiments, the first and second galvanic potentials may be configured to achieve, at least approximately, a desired copper ion elution rate for the intrauterine device.
